Abstract: A combination cutting blade/raking device where the blade portion slices weeds off under the soil, thereby effectively killing the plant, and a raking portion collects the uprooted weeds. The blade and rake also flatten the surface of the soil. The raking section of the invention can be lifted independently of the cutting blade. The cutting blade is reversible so a user of the invention can cut twice as much area before having to remove the blade for sharpening. The blade is slightly curved in cross section, allowing for a smoother cutting path through the soil.

Abstract: Agricultural mechanized system for pulling-off and chopping stubs of cotton plants and similar agricultures, especially of a agricultural mechanized system coupled to a tractor, to plow and pull off the stubs preferably from the cotton agricultures and similar cultures firmly buried, which comprises a set of plows (10) provided with a pair of cutting wheels (14) and a pair of adjustable plowing blades (16 and 16?) between a first position above the ground and a final position of penetration in the ground which is longer than the radicular portion depth of the referred stubs, a chopper set (12) with blades (96) which chop the referred stubs into a particulate material into smaller fragments forming a layer of inert organic matter with at least a stub pulling-off set (11) arranged between the referred plowing set (10) and chopper set (12) mounted upon a support frame (2) on wheels (7 and 8).

Abstract: The invention relates to a harvester for harvesting a root crop, and more in particular for harvesting potatoes. For that purpose, the root crop and attached soil material is guided towards a rotating helically shaped conveyor track (4). This conveyor track (4) is provided with sieve openings, which remove attached soil material from the root crop during transportation. Preferably, the helically shaped conveyor track is made of synthetic tubing or rods, which can be bought on a roll.

Abstract: A rock picker includes a picker grate having a plurality of picker bars extending in a curved path forwardly and downwardly to a forwardmost end for engaging the rocks and lifting them onto the picker grate. A conventional sweeping reel sweeps the rocks to a hopper. The forward end of each of the grate bars includes a portion consisting of a vertical plate parallel to the direction of movement together with a rotating rod which extends across the full width of the picker and is supported by the cup-shaped forward ends of the grate bars. The rod improves the rock picking action and also allows the clearing of trash between the rod and the vertical plate portions exposed at the front of the grate bars. A second embodiment includes a further roe positioned with a trip mechanism forwardly and downwardly of the first rod.

Abstract: An apparatus for uprooting and shredding cotton plants after harvest includes a below ground cutting blade having a forward cutting edge inclined rearwardly and to one side of the implement, which blade cooperates with an oppositely inclined above ground trash bar to uproot cotton plants and deposit them on the ground transversely of the direction of travel of the apparatus.

Abstract: Apparatus for breaking rock found in soil, such as in a field used for farming, includes a hood-like housing. A work shaft and a drum are positioned under the hood with the work shaft preceding the drum in the normal direction of movement of the apparatus. Flail-like parts are located on the outer surface of the work shaft and travel along a circular path. Prongs are provided on the drum and also move around a circular path. The circular path of the prongs is located lower than the circular path of the flail-like parts and at their closest point the circular paths are approximately tangent to one another where rock or other material is transferred from the prongs to the flail-like parts.

Abstract: This invention is concerning a machine for rock removal and soil cultivation of newly broken or established farming areas. The machine picks up soil and rocks to a significant depth, and by a mixing and grinding process, breaks up sod, roots, and lumps of soil and by a classification process returns the size reduced material and small rocks to the ground, and retains the larger rocks.
